Hypertrophy of tongue papillae

This code describes an abnormal enlargement or overgrowth of the taste buds (papillae) on the surface of the tongue. This condition can manifest as various forms, such as hairy tongue (lingua villosa nigra) or transient lingual papillitis, and may involve changes in color or texture.

Use this code when documentation specifies hypertrophy, enlargement, or overgrowth of the tongue papillae. This includes conditions like black hairy tongue, white hairy tongue, or other forms of papillary hyperplasia. Supporting documentation should clearly indicate the presence of enlarged papillae on the tongue.

• Differentiate from other tongue disorders like glossitis (inflammation of the tongue) or geographic tongue, which have distinct codes.
• Look for specific terms such as "hairy tongue," "lingua villosa," or "papillary hyperplasia of tongue."
• Consider any associated symptoms or underlying causes documented, but this code specifically addresses the papillary hypertrophy.
